TECHNICAL DATA
IN74ACT175
Quad D Flip-Flop with
Common Clock and Reset
High-Speed Silicon-Gate CMOS
The IN74ACT175 is identical in pinout to the LS/ALS175,
HC/HCT175. The IN74ACT175 may be used as a level converter for
interfacing TTL or NMOS outputs to High Speed CMOS inputs.
This device consists of four D flip-flops with common Reset and
Clock inputs, and separate D inputs. Reset (active-low) is asynchronous
and occurs when a low level is applied to the Reset input. Information at a
D input is transferred to the corresponding Q output on the next positive-
going edge of the Clock input.
